Compact, lightweight, and reliable automatic air sampling pump for GASTEC detector tubes and sorbent tubes.

• Flow range 50 - 500 ml/min
• 10 - 500 ml/min is available when volume mode (When set to 10 - 49 ml/min, the intermittent operation is performed at 50 ml/min)
• Fixed flow function automatically regulates load changes
• Flow rate, sampling time, and integrated volume are displayed on the same screen simultaneously
• Quiet operation with low noise
• Automatic start enables sampling to begin after a preset time
• Five sampling settings can be saved with the program mode
• Accuracy: Instantaneous flow rate 50 - 500 ml/min ±5%

Real-time flow volume and integrated flow volume are automatically corrected to the values for 20 °C (68 °F) or 25 °C (77 °F).
